However, the cylinder-wall thickness T1 is not limited to this embodiment. The cylinder-wall thickness T1 can be at least partly uneven at positions corresponding to the recesses 126. In such an embodiment, radial positions of bottoms of the recesses 126 are at least partly uneven relative to the cylinder bore 32. In a case where the thickness of the cylinder wall 128 is uneven, for example, the cylinder-wall thickness T1 is defined as a maximum thickness of the cylinder wall 128 defined in the radial direction of the cylinder bore 32.
The cylinder bore 32 has an inner diameter DM1. The inner diameter DM1 is set within a range from 6 mm to 15 mm. Preferably, the inner diameter DM1 is set within a range from 9 mm to 12 mm. In this embodiment, the inner diameter DM1 is 12 mm. A ratio of the cylinder-wall thickness T1 to the inner diameter DM1 is equal to or larger than 5% and equal to or smaller than 40%. However, the ratio of the cylinder-wall thickness T1 to the inner diameter DM1 is not limited to this embodiment.
The base member 12 includes at least one rib 130. In this embodiment, the at least one rib 130 includes a plurality of ribs 130. The at least one rib 130 is provided between adjacent two of the recesses 126. The at least one rib 130 has a thickness T2 equal to or larger than 0.2 mm and equal to or smaller than 3 mm. The thickness T2 of the rib 130 is preferably equal to or larger than 0.4 mm and equal to or smaller than 2 mm. In this embodiment, the thickness T2 of the rib 130 is equal to 1 mm. In another embodiment, for example, the thickness T2 of the rib 130 can be equal to 0.45 mm. Furthermore, the thickness T2 of the rib 130 is equal to or smaller than the cylinder-wall thickness T1. However, the thickness T2 of the rib 130 is not limited to this embodiment. A total number of the ribs 130 is not limited to this embodiment. The thickness T2 of the ribs 130 can be at least partly uneven at positions corresponding to the ribs 130.

The base member 12 includes at least one additional rib 136. In this embodiment, the at least one additional rib 136 includes a plurality of additional ribs 136. The at least one additional rib 136 is provided between adjacent two of the additional recesses 132. The at least one additional rib 136 has a thickness T4 equal to or larger than 0.2 mm and equal to or smaller than 3 mm. The thickness T4 of the additional rib 136 is preferably equal to or larger than 0.4 mm and equal to or smaller than 2 mm. In this embodiment, the thickness T4 of the additional rib 136 is equal to 1 mm. In another embodiment, for example, the thickness T4 of the additional rib 136 can be equal to 0.45 mm. Furthermore, the thickness T4 of the additional rib 136 is equal to or smaller than the reservoir-wall thickness T3. However, the thickness T4 of the additional rib 136 is not limited to this embodiment. A total number of the additional ribs 136 is not limited to this embodiment. The thickness T4 of the additional ribs 136 can be at least partly uneven at positions corresponding to the additional ribs 136.

In this embodiment, the base member 12 includes the recesses 126 and the additional recesses 132. However, the recesses 126 can be omitted from the base member 12, and the additional recesses 132 can be omitted from the base member 12. Namely, the base member 12 can include only the recesses 126 provided about the cylinder bore 32 without the additional recesses 132. The base member 12 can include only the additional recesses 132 provided about the reservoir bore 50 without the recesses 126.
With the bicycle operating device 10, the at least one recess 126 reduces deformation of an inner peripheral surface of the cylinder bore 32 during manufacturing process of the base member 12 made of the resin material.

The term “comprising” and its derivatives, as used herein, are intended to be open ended terms that specify the presence of the stated features, elements, components, groups, integers, and/or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers and/or steps. This concept also applies to words of similar meaning, for example, the terms “have,” “include” and their derivatives.
The terms “member,” “section,” “portion,” “part,” “element,” “body” and “structure” when used in the singular can have the dual meaning of a single part or a plurality of parts.
The ordinal numbers such as “first” and “second” recited in the present application are merely identifiers, but do not have any other meanings, for example, a particular order and the like. Moreover, for example, the term “first element” itself does not imply an existence of “second element,” and the term “second element” itself does not imply an existence of “first element.”
The term “pair of,” as used herein, can encompass the configuration in which the pair of elements have different shapes or structures from each other in addition to the configuration in which the pair of elements have the same shapes or structures as each other.
The terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein.
Finally, terms of degree such as “substantially,” “about” and “approximately” as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. All of numerical values described in the present application can be construed as including the terms such as “substantially,” “about” and “approximately.”
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
